Medigap or Medicare Supplements

Every Medicare Supplement Inursance policy, also referred to as Medigap insurance, must follow federal and state laws designed to protect you, and it must be clearly identified as "Medicare Supplement Insurance".  Insurance companies can sell you only a "standardized" policy identified in most states by letters.  Medigap, is health insurance sold by insurance companies to help fill the “gaps” in Original Medicare Plan coverage (also called Part A and Part B).  These expenses can include copayments, deductibles, and coinsurance. Some plans even help cover medical costs incurred during travel to other countries.  If you have Original Medicare and you buy a Medigap policy, Medicare will pay its share of the  Medicare-ap proved amount for covered health care costs. Then your Medigap policy pays its share.   But it doesn’t cover everything. In general, services like vision and dental care, hearing aids, long-term care, and private nursing are not covered. 

There are 10 different plans which are named using a letter of the alphabet: A, B, C, D, F, G, K, L, M, and N. Each plan includes a unique set of benefits, which are standardized by law.


You must have Medicare Part A and Part B to purchase a medigap policy. You will have to pay the monthly Medicare Part B premium. In addition, you will have to pay a premium to the Medigap insurance company.

The best time to buy a Medigap policy is during your 6-month Medigap open enrollment period. During that time you can buy any Medigap policy sold in your state, even if you have health problems. This period automatically starts the month you're 65 and enrolled in Medicare Part B (Medical Insurance). After this enrollment period, you may not be able to buy a Medigap policy.  

Things to know about Medigap policies:

  • You must have Medicare Part A and Part B
  • You pay the private insurance company a monthly premium for your Medigap policy in addition to the monthly Part B premium that you pay to Medicare.
  • A Medigap policy only covers one person. If you and your spouse both want Medigap coverage, you'll each have to buy separate policies.
  • You can buy a Medigap policy from any insurance company that's licensed in your state to sell one.
  • Any standardized Medigap policy is guaranteed renewable even if you have health problems. This means the insurance company can't cancel your Medigap policy as long as you pay the premium.
  • Some Medigap policies sold in the past cover prescription drugs, but Medigap policies sold after January 1, 2006 aren't allowed to include prescription drug coverage. If you want prescription drug coverage, you can join a Medicare Prescription Drug Plan (Part D).
